CPA / CCF / CLP-C / CSB-F / CSB-M fixed LV capacitors with protection and switching
Country: Spain · Model: CPA / CCF / CLP-C / CSB-F / CSB-M
Fixed LV capacitors with built-in protection and switching for individual compensation of motors and transformers with constant load. The range includes CPA with a circuit breaker, CCF with a contactor and fuses, CLP-C and CSB-F/CSB-M, with stages up to 120 kvar at 440 V. They are installed near the load and do not need a separate panel with protection devices.

Description
CPA-120-440 gives 120 kvar at 440 V (100 kvar at 400 V) and is protected by a 250 A breaker with a breaking capacity of 50 kA, cable 95 mm². CCF-100-440 has 100 kvar at 440 V (80 kvar at 400 V), a rated current of 131 A, 160 A fuses rated 120 kA, a 70 mm² cable and 230 V contactor control, and CCF stages are made from 10 to 100 kvar. CLP-C-44/25 is a CLZ capacitor with a breaker and contactor in an IP20 enclosure, 25 kvar at 440 V, 33 A, 6 kA. The insulation is 3/15 kV, the tolerance ±10 %, dielectric losses are below 0.2 W/kvar, total losses below 0.5 W/kvar, and discharge is 75 V in 3 min. The rated voltage is 400/440 V, 50 Hz. Overvoltages of 10 % are permissible for 8 h per day, 15 % up to 15 min, 20 % up to 5 min, 30 % up to 1 min, with a continuous overload of 1.3 In. Temperature class D (daily average 45 °C, maximum 55 °C, minimum −25 °C), humidity up to 80 %.
How to choose
First the type of switching is determined. For a constant load CPA with breaker protection is suitable, and if the stage must be switched by a signal, CCF or CLP-C with a contactor is used. The power is selected by the reactive power of the consumer, taking the voltage into account, since at 400 V a capacitor gives less than its 440 V rating, for example 100 kvar instead of 120 kvar for CPA-120-440. For automatic regulation across a workshop it is better to install a computer SMART III controller.
